Mr Smith who is the Chair of the House of Commons Administration Committee said 120,000 plastics have been removed from Parliament this year.
Plastic straws and cutlery have been replaced with more sustainable alternatives, and a packaging sustainability policy has been introduced.
The UK Parliament stopped the sale and purchase of single-use plastic water bottles in October 2018.
The UK Parliament implemented a comprehensive plan to drastically reduce its consumption of single-use plastics across the Parliamentary Estate, including the House of Commons and the House of Lords.
Despite the progress, Mr Smith told The Commons that the Administration Committee will not get complacent and look at further opportunities to reduce plastic consumption across the estate.
Mr Smith said: “Parliament is taking action to reduce single-use plastics across our estate. This includes removing plastic bottles of water from sale, eliminating about 120,000 of them each year. We have also replaced plastic straws and cutlery with more sustainable alternatives and increased the use of reusable and recyclable products. Parliament has also introduced a packaging sustainability policy for our procurement, which incentivises suppliers to reduce single-use plastics. We continue to look at further opportunities to reduce plastic consumption across our estate.
“As I have set out, Parliament has made significant progress in reducing single-use plastics across the estate. For example, to minimise the environmental impact, single-use plastic cups are now made from biodegradable material, and we do bags of stuff on composting. However, we are not complacent, and we will continue to identify further opportunities to reduce unnecessary plastic use. I thank my hon. Friend for raising this question, and I will ask officers to come back to us both on our plastic use reduction plan.”
When introduced 2018, Parliament said the steps were part of a “wider strategy to reduce the impact of the organisation on the natural environment, including ambitious targets around energy efficiency, water consumption and reducing waste.
