Gas heating ban for new homes from 2025?
In addition to heat pumps, the homes will be insulated to "world-leading" standards.?
Philip Hammond is trying to address the concerns of children protesting climate change.
The Green Party of England and Wales hailed the measure, but criticised the Chancellor's lack of action on climate change.
A large percentage of the housing stock will be draughty for decades, so it is imperative that we take action to reduce emissions from traffic, planes, and existing draughty homes.
In response, Mr Hammond offered an inadequate idea for reducing aviation emissions.
Among the plans he's working on is to require all airlines to offer passengers the option of planting trees to offset their emissions.
The scheme is controversial, and Greenpeace urged the government to introduce a tax on frequent fliers instead.
In tackling the climate emergency, the Chancellor needs to think much bigger, according to Greenpeace's Mel Evans.
There is a need for serious money behind serious policies in order to address problems like the shoddy state of our existing housing stock and the rapid adoption of electric vehicles.
Rather than 2040, we should ban the sale of new petrol and diesel cars and vans by 2030."
Partha Dasgupta, a Cambridge economics professor, was chosen by the Chancellor to lead a global commission to estimate the economic value of nature.
This body is hoped to influence governments' views of nature in the way the Stern review of climate economics in 2006 influenced global discussions on climate change.
Friends of the Earth's Dave Timms reacted to Wednesday's Spring Statement by saying: "Instead of addressing climate change at the center of economic policy-making, the Chancellor merely fiddles at the margins."
In order to cut emissions, the nation's children are calling for tough action. Mr Hammond needs to listen more carefully to their lessons."
