General election: leaders debate climate emergency on Channel 4 – live news

Claim: Jeremy Corbyn is promising to plant 2bn trees by 2040

Reality: The government must already adhere to the Committee for Climate Change target of 1.5bn trees by 2050. Jeremy Corbyn’s pledge is for more trees in 20 rather than 30 years. This means 100m trees must be planted a year to expand woodland and make up for losses. This is ambitious, but is not impossible and not out of synch with what experts say.

Claim: Nicola Sturgeon said that last year 85% of the UK’s tree planting took place in Scotland.

Reality: That is correct but the Scottish government has repeatedly failed to meet its national tree-planting targets, set at 10,000 hectares (24,700 acres) a year from 2010.

Official data shows that from 2010 to 2017, Scotland’s planting rate averaged 6,800 hectares a year, well below target. Of that, only 820 hectares was planted annually by Forest Enterprise, the government-funded forestry agency, and the rest by private companies or charities.

The overall target was met for the first time last year, when 11,200 hectares were planted.

Sturgeon’s government has agreed to greatly increase tree planting in line with recommendations from the UK committee on climate change, which says Scotland can reach net zero five years early than the UK as a whole partly because it has much greater scope for tree planting. However, the Scottish government has yet to decide on how to do so.

Claim: Siân Berry, co-leader of the Green Party claims that pasture land used for meat need to be changed to reach carbon neutrality.

Reality: The government’s advisory Committee for Climate Change says a 20-50% reduction in beef and lamb pasture could release 3-7m hectares of grassland from the current 12m hectares in the UK.

Plaid Cymru’s Adam Price claimed that this did not mean fewer cattle because grass can bank carbon.

But the CCC found that un-needed grassland could instead grow forests and biofuels that would help to soak up CO2.
