The PAC has warned, however, that the government has not laid out how all these measures will be paid for, or by whom, with no plan to report on spending in pursuit of net zero.
“To publish policy without commensurate funding merely amounts to an aspiration not a real intention by [the] government,” the report warned.
MPs said clarity on costs to ordinary people is crucial at a time when “many people are worries about their energy bills”.
The committee made several recommendations to the government, including calling on the Treasury to set out how progress on implementing net zero policies will be reported.
The PAC report also warned the government has failed to engage consumers, investors and local governments when it comes to behaviour changes and policies for net zero – and needs to do so if it wants to hit the 2050 target.
Hillier added: “[The] government is relying heavily on rapidly changing consumer behaviours and technological innovations to drive down the costs of green options, but it is not clear how it will support and encourage consumers to purchase greener products or incentivise businesses and drive change.”
Responding to the report, Rebecca Newsom, head of politics at Greenpeace UK said: “The key thing this report skewers isn’t net zero, which remains essential, but the government’s failure to chart a clear way forward with consistent, appropriate policies and investment which will minimise costs and protect the most vulnerable in society.”

Eco-friendly gift hampers that make a positive impact
The Big Issue has collaborated with Social Stories Club to create limited edition gift hampers. Packed full of treats made by social ventures, this hamper would make the perfect gift for the festive season.
Ben Margolis, interim director of The Climate Coalition added: “Achieving net zero and ensuring a healthy, safer climate and environment for future generations is the greatest challenge the government and wider population face.
“We need an all of government approach with the prime minister leading and the chancellor funding the transformation. However, we’re yet to see that in action and stop-start measures and policies are hindering progress and leaving the door open for doubters.”
