Committee on Climate Change letter condemns government’s ‘dash for gas’



The Committee on Climate Change (CCC) has called for a rethink over the government’s plans for the UK to rely heavily on gas in a letter to energy secretary Ed Davey. It says doing this would be “incompatible” with meeting legally-binding carbon reduction targets.

The letter, which is signed by eight names including recently installed CCC chair Lord Deben and chief executive David Kennedy, says the government would be failing to abide by the Climate Change Act by committing to gas.

It highlights the government’s “ambivalent position” over the choice between low-carbon or gas-fired power systems, and says that as a result of this uncertainty, “the cases for low-carbon business development, capital allocation, innovation and supply chain investment are undermined, damaging prospects for required low-carbon investments.”

The CCC also called for decarbonisation of the electricity market by 2030, something that Davey said the government was “currently considering” in a statement responding to the letter.

We are absolutely committed to meeting our statutory carbon budgets”, the energy secretary added. 

“That is why we are pushing through ambitious reforms to overhaul existing old fossil fuel power plants, replacing them with new low-carbon forms of power generation.

A fifth of our power stations are closing over the next decade and we need to build a diverse mix of all the technologies to keep the lights on and lower our emissions.

Davey went on to say that gas would indeed have a role in Britain’s future energy mix, but that it would be gradually phased out in favour of low-carbon generation sources.

We have always said this will include gas fired plant, which is quick to build and flexible”, he said.

 After 2030 we expect that gas will only be used as back up, or fitted with Carbon Capture and Storage technology. But, alongside up-scaling of renewables, nuclear new build, and eventually with carbon capture and storage, gas has an important role to play in the transition to a low carbon grid.‪

Our gas generation strategy work is about providing certainty to investors to ensure sufficient investment comes forward, whilst also living within our legally binding carbon budgets.”

The response to the CCC’s letter from the green sector has been almost completely positive. Gaynor Hartnell, chief executive of the Renewable Energy Association, said, “This important letter from the CCC clearly explains one of the reasons confidence is flagging across the renewable power sector.

Gas can be a friend of renewables, if used strategically to support the transition to a low-carbon future. That is the approach we would like to see in the Department of Energy and Climate Change’s forthcoming gas strategy.

In the long run, renewables will provide a cheaper, as well as more secure and sustainable, energy future. The case for renewables is not just or even mainly about saving the planet – it’s about restoring the UK economy to prosperity and maintaining global competitiveness in the 21st century.

Government needs to provide consistent political support and a stable investment climate if it is to achieve its decarbonisation objectives. It is very encouraging that the new chair of the CCC Lord Deben has moved so quickly to articulate this important message.”

The government’s energy bill, published in May, promised to ensure secure, clean and affordable electricity, but its strong commitment to gas threatens to scupper this ideal just months after its initial pledge.

The chancellor, George Osborne, had previously championed gas as “the largest single source of our electricity in the coming yearsin his budget statement – a declaration that had green groups up in arms.

Also welcoming the CCC’s letter, Friends of the Earth’s head of campaigns Andrew Pendleton, said, “This is a very stark warning the government cannot ignore: an unabated dash for gas is incompatible with tackling climate change and threatens the UK’s growing green economy, which already employs almost 1m people.

The energy bill must contain a clear target to decarbonise the UK’s electricity system by 2030, to give one of the few growth areas of our economy a massive boost and reaffirm the Government’s commitment to tackling climate change.

Investing in clean British energy from the wind, waves and sun will reduce the nation’s dependence on increasingly expensive gas and create tens of thousands more jobs.”

Indeed, Ernst & Young’s Country Attractiveness Indices found earlier this year that although investment in clean energy was at its lowest level since 2009 in the first part of 2012, the positive long-term outlook for the sector continued to overshadow any pessimism.

Will Self-Driving Cars Be Better for the Environment?

Technologists, engineers, lawmakers, and the general public have been excitedly debating about the merits of self-driving cars for the past several years, as companies like Waymo and Uber race to get the first fully autonomous vehicles on the market. Largely, the concerns have been about safety and ethics; is a self-driving car really capable of eliminating the human errors responsible for the majority of vehicular accidents? And if so, who’s responsible for programming life-or-death decisions, and who’s held liable in the event of an accident?

But while these questions continue being debated, protecting people on an individual level, it’s worth posing a different question: how will self-driving cars impact the environment?

The Big Picture

The Department of Energy attempted to answer this question in clear terms, using scientific research and existing data sets to project the short-term and long-term environmental impact that self-driving vehicles could have. Its findings? The emergence of self-driving vehicles could essentially go either way; it could reduce energy consumption in transportation by as much as 90 percent, or increase it by more than 200 percent.

That’s a margin of error so wide it might as well be a total guess, but there are too many unknown variables to form a solid conclusion. There are many ways autonomous vehicles could influence our energy consumption and environmental impact, and they could go well or poorly, depending on how they’re adopted.

Driver Reduction?

One of the big selling points of autonomous vehicles is their capacity to reduce the total number of vehicles—and human drivers—on the road. If you’re able to carpool to work in a self-driving vehicle, or rely on autonomous public transportation, you’ll spend far less time, money, and energy on your own car. The convenience and efficiency of autonomous vehicles would therefore reduce the total miles driven, and significantly reduce carbon emissions.

There’s a flip side to this argument, however. If autonomous vehicles are far more convenient and less expensive than previous means of travel, it could be an incentive for people to travel more frequently, or drive to more destinations they’d otherwise avoid. In this case, the total miles driven could actually increase with the rise of self-driving cars.

As an added consideration, the increase or decrease in drivers on the road could result in more or fewer vehicle collisions, respectively—especially in the early days of autonomous vehicle adoption, when so many human drivers are still on the road. Car accident injury cases, therefore, would become far more complicated, and the roads could be temporarily less safe.


Deadheading is a term used in trucking and ridesharing to refer to miles driven with an empty load. Assume for a moment that there’s a fleet of self-driving vehicles available to pick people up and carry them to their destinations. It’s a convenient service, but by necessity, these vehicles will spend at least some of their time driving without passengers, whether it’s spent waiting to pick someone up or en route to their location. The increase in miles from deadheading could nullify the potential benefits of people driving fewer total miles, or add to the damage done by their increased mileage.

Make and Model of Car

Much will also depend on the types of cars equipped to be self-driving. For example, Waymo recently launched a wave of self-driving hybrid minivans, capable of getting far better mileage than a gas-only vehicle. If the majority of self-driving cars are electric or hybrids, the environmental impact will be much lower than if they’re converted from existing vehicles. Good emissions ratings are also important here.

On the other hand, the increased demand for autonomous vehicles could put more pressure on factory production, and make older cars obsolete. In that case, the gas mileage savings could be counteracted by the increased environmental impact of factory production.

The Bottom Line

Right now, there are too many unanswered questions to make a confident determination whether self-driving vehicles will help or harm the environment. Will we start driving more, or less? How will they handle dead time? What kind of models are going to be on the road?

Engineers and the general public are in complete control of how this develops in the near future. Hopefully, we’ll be able to see all the safety benefits of having autonomous vehicles on the road, but without any of the extra environmental impact to deal with.

New Zealand to Switch to Fully Renewable Energy by 2035

New Zealand’s prime minister-elect Jacinda Ardern is already taking steps towards reducing the country’s carbon footprint. She signed a coalition deal with NZ First in October, aiming to generate 100% of the country’s energy from renewable sources by 2035.

New Zealand is already one of the greenest countries in the world, sourcing over 80% of its energy for its 4.7 million people from renewable resources like hydroelectric, geothermal and wind. The majority of its electricity comes from hydro-power, which generated 60% of the country’s energy in 2016. Last winter, renewable generation peaked at 93%.

Now, Ardern is taking on the challenge of eliminating New Zealand’s remaining use of fossil fuels. One of the biggest obstacles will be filling in the gap left by hydropower sources during dry conditions. When lake levels drop, the country relies on gas and coal to provide energy. Eliminating fossil fuels will require finding an alternative source to avoid spikes in energy costs during droughts.

Business NZ’s executive director John Carnegie told Bloomberg he believes Ardern needs to balance her goals with affordability, stating, “It’s completely appropriate to have a focus on reducing carbon emissions, but there needs to be an open and transparent public conversation about the policies and how they are delivered.”

The coalition deal outlined a few steps towards achieving this, including investing more in solar, which currently only provides 0.1% of the country’s energy. Ardern’s plans also include switching the electricity grid to renewable energy, investing more funds into rail transport, and switching all government vehicles to green fuel within a decade.

Zero net emissions by 2050

Beyond powering the country’s electricity grid with 100% green energy, Ardern also wants to reach zero net emissions by 2050. This ambitious goal is very much in line with her focus on climate change throughout the course of her campaign. Environmental issues were one of her top priorities from the start, which increased her appeal with young voters and helped her become one of the youngest world leaders at only 37.

Reaching zero net emissions would require overcoming challenging issues like eliminating fossil fuels in vehicles. Ardern hasn’t outlined a plan for reaching this goal, but has suggested creating an independent commission to aid in the transition to a lower carbon economy.

She also set a goal of doubling the number of trees the country plants per year to 100 million, a goal she says is “absolutely achievable” using land that is marginal for farming animals.

Greenpeace New Zealand climate and energy campaigner Amanda Larsson believes that phasing out fossil fuels should be a priority for the new prime minister. She says that in order to reach zero net emissions, Ardern “must prioritize closing down coal, putting a moratorium on new fossil fuel plants, building more wind infrastructure, and opening the playing field for household and community solar.”

A worldwide shift to renewable energy

Addressing climate change is becoming more of a priority around the world and many governments are assessing how they can reduce their reliance on fossil fuels and switch to environmentally-friendly energy sources. Sustainable energy is becoming an increasingly profitable industry, giving companies more of an incentive to invest.

Ardern isn’t alone in her climate concerns, as other prominent world leaders like Justin Trudeau and Emmanuel Macron have made renewable energy a focus of their campaigns. She isn’t the first to set ambitious goals, either. Sweden and Norway share New Zealand’s goal of net zero emissions by 2045 and 2030, respectively.

Scotland already sources more than half of its electricity from renewable sources and aims to fully transition by 2020, while France announced plans in September to stop fossil fuel production by 2040. This would make it the first country to do so, and the first to end the sale of gasoline and diesel vehicles.

Many parts of the world still rely heavily on coal, but if these countries are successful in phasing out fossil fuels and transitioning to renewable resources, it could serve as a turning point. As other world leaders see that switching to sustainable energy is possible – and profitable – it could be the start of a worldwide shift towards environmentally-friendly energy.
