Six organisations have been fined for failing to comply with climate change regulations, according to the Environment Agency.
The penalties, totaling more than £40,000, are for breaches of the carbon reduction commitment scheme (CRC).
The largest fines, of £13,500 each, were handed to food and pharmaceutical firm ALS Testing Services and retailer 99p Stores. The firms were fined for failing to submit their annual reports for the 2014/15 compliance year by 31 July 2015 deadline.
Leisure centre operator Aquaterra Leisure was fined £250 for not surrendering enough allowances to cover its emission in 2013/14, and £500 for failing to submit its annual report for the following year on time.
The University of Hull had to pay £6,150 for not submitting an annual report for 2014/15 on time, while Mansion Student Accommodation Fund was fined £2,580 for the same reason.
Lastly, film and video firm Deluxe Laboratories was fined £5,000 for failing to pay for sufficient allowances to cover its carbon emissions for 2014/15 on time.
The announcement takes the number of firms fined for offences relating to the CRC to 29. The scheme is due to be scrapped in 2019 after the government announced last year that it would reduce the number business energy efficiency tax schemes.
